5x – 2x = 12
How do I solve

Answers

Answer 1

Answer:

4

Step-by-step explanation:

Replace X with 4

(5*4)-(2*4) = 12

Answer 2

Answer:

x =4

Step-by-step explanation:

5x - 2x =12 (Subtract 5x - 2x and you'll get 3x)

3x = 12 (Now divide by 3 from both sides to get x)

x = 12/3 (Now that you got x, you want to simplify)

x = 4 (12 divided by 3 is 4)

Answer:

180 degrees.

Step-by-step explanation:

The measure of angle EDC is equal to the sum of the angles of EDQ and QDC.

In  this problem, angle EDQ is equal to 30 degrees, and angle QDC is equal to 150 degrees.

So, angle EDC is equal to 150 + 30, or 180 degrees.

We know that the intersection of three given sets represents the largest set which consists of all the elements that are common to all the sets.

What is the symbol of the intersection of the sets:

The intersection of sets is denoted by the symbol '∩'.

Determining the  intersection of the sets:

Given

X= {1,2,4,6,7,8,9}

Answer:

The missing value of x in this arithmetic sequence is "1"

Step-by-step explanation:

Since this is an arithmetic sequence that means that when we get from one term to the next one we always add/substract the same number each time.

In our case each time we need to find the next term we just add 6 to the current term. For example, after 13 we have 19 which is essentially 13 + 6.  

From this we know in order to get from x to 7 we added 6, now know this we can make an equation...

x + 6 = 7

And now we just solve it...

x + 6 = 7

x = 7 - 6

x = 1

Previous 20 Item 20 The width of a rectangular room is 60% of its length. The length of the room is 10 feet. What is the area of the room

Answers

Answer: A=60 square feet

Explanation: w=10*0.6=6 ft.

A=lw

A=10*6=60 square feet.

Answer: 60 feet²

Step-by-step explanation:

The width of the rectangular room is 60% of the length which is 10 feet.

The width is therefore:

= 60% * 10

= 6 feet

The area of a rectangle is calculated by the formula:

= Length * Width

Area there is:

= 10 * 6

= 60 feet²

Ifx += 5, find the value of x?

Answers

didn't undrestood the question

Answer:

if x + 0 = 5, the value of x is 5.

Step-by-step explanation:

we discard 0 since it is of no value in the equation. thus, x = 5. i'm not sure if the one next to the plus sign is 0, since there's nothing there, but we'll assume it's 0. however, if it turns out to be another number, just transpose the other number next to 5 (it would be negative), and subtract. that will be your x.

Meghans family is going on a road trip that is 621 miles. They plan to split the trip up equally into 3 days. April's family is also going on a road trip. They will drive 726 miles and split the trip up equally between 3 days. How many more miles per day will Aprils family drive than Meghan's

Answers

Answer:

35 miles more per day than Meghan's family

Step-by-step explanation:

In order to solve this problem, we need to divide the total number of miles that each family is going to drive by the 3 days that they will spend doing so. Once we do this we simply subtract the results from one another which will tell us the difference in miles per day that each family will drive.

Meghan:  621 / 3 = 207 miles per day

April:  726 / 3 = 242 miles per day

242 - 207 = 35 miles per day

Finally, we can see that April's family will drive 35 miles more per day than Meghan's family
